马力常被用来量度汽车引擎的性能

新闻导读:What is the horsepower? When it comes to the performance of the car, people first thought is horsepower. What is the horse power? HP is one of the power unit, instead of the power unit. What is power? Power is defined as: the work per unit time. In other words, for the car, is produced in a certain period of time to supply the car depends on the energy of motion. Again for example, the same work, someone may soon finished, some slow, fast do says he has done in each period of time of work, must be more than people in the slow, we call it high work efficiency. The same, at the same time, can provide the more energy of the engine, the greater the power of it, is the greater the power.

汽车的动力来自引擎,用什么来量度引擎的性能呢?一般多以功率(马力)、扭力衡量之。
Auto power from the engine, with what to measure the performance of the engine? And more generally to power (HP), torque measurement.


什么是马力?说到车的性能,一般人第一个想到的就是马力。什么是马力呢?马力是功率单位之一,而不是力量的单位。什么是功率呢?功率的定义是:单位时间内所作的功。换句话说,对车子来讲,就是在一定的时间内所产生供给车子运动的能量多寡。再打个比方,同样的工作量,有人可能很快做完,有人很慢,做得快的人表示他在每一段时间内所完成的工作量,一定比慢的人多,我们称之为工作效率高。相同的,在同样时间内,能够提供越多能量的引擎,它的功率越大,也就是马力越大。

一般都说「马力大的车比较够力」,当然,马力的确和引擎的出力有关,但是我们可以就一个简单的物理学公式,认识马力(功率)、力量与速度间的关系。式子是这样的:功率=力量*速度。举例来说,一个很有力的人,能在5分钟内搬5包白米爬三层楼;而另一个人比较没力,但脚程很快,同样的路程虽只能搬一包白米,却能在1分钟达成。经计算,有力但走得慢的人,和没力但走得快的人,其实功率是一样的。所以同样是300hp马力的车,跑车就能有很高的极速,而货车则有很大的载重量。
Generally said "high-powered car is enough to force", of course, indeed linked to the output of the engine horsepower, but we can be just a simple formula of physics knowledge power (power), the relationship between the power and speed. Formula is as follows: power = * speed strength. For example, a very powerful person, can in 5 minutes with 5 packages up three floors of white rice, And another person is not force, but foot lift soon, although the same journey can only carry a bag of rice, in 1 minute. Through calculation, forceful but walk slowly, but people walk fast and didn t force, power is actually the same. So is also a HP 300 - horsepower car, sports car can have very high speed, while the truck there is a lot of weight.


引擎测试标准。常见的引擎测试标准有JIS、SAE、EEC、DIN四种;它们分别为日本、美国、欧盟、德国所采行的测试标准;其中DIN已经较少被欧洲车厂所采用了。由于JIS、SAE、EEC三种测试标准的内容相近,使得引擎的测试结果也几乎相同。汽车制造厂会因为汽车商品的性能需求或是为了符合污染排放标准,去对引擎做不同的周边安排以及调校,使同一型的引擎在不同的国家或车型上会有不同的马力值。
Engine test standard. Common engine test standard JIS, SAE, EEC, DIN four; They respectively are adopted by Japan, the United States, the European Union, Germany testing standards; One less DIN has been adopted by European automakers. Because JIS, SAE, EEC testing standard of the content of three close, make the engine test results is almost the same. Car manufacturers would because car performance requirements of the goods or to comply with pollution emission standards, to the engine around doing different arrangement and adjustment, to make the same type of engines or models in different countries have different values.


在引擎的测试方式还有总马力和净马力二种测试方式。总马力和净马力的不同处在于,总马力是在引擎没有附挂任何附加设备时所做的测量值。净马力是引擎在附挂发电机、水泵、排气管....等附加设备后所做的测量值。目前引擎测试几乎都是净马力测试。
In the engine test and the total and net horsepower two test methods. Always Marion and net is different in that it is the total power in engine suspended without any additional equipment of measured values. Net horsepower is in suspended generator, water pump, engine exhaust pipe... Additional equipment such as the measured value. Now, almost are net horsepower engine test test.


德制日制如何换算。由于日本JIS在1994年施行修改后的引擎测试标准,使得JIS与EEC及SAE的测试标准极为相近,使得同一个引擎在JIS、SAE、EEC的测试条件下,会有几乎相同的输出数据。而大家最关心的议题,不外是各种标准之间的马力如何换算,由于德制 (DIN) 标准与其他测试标准的设定不同,不单纯是单位之间的换算问题,所以,根本无法换算。
DE the day how to conversion. Because Japan JIS in 1994, the modified engine test standard, makes the test standard of JIS, EEC and SAE is very close, make the same engine in JIS, SAE, EEC test conditions, there will be almost the same output data. And everybody s most concerned topics, choosing between various standard horsepower how conversion, because of the German system (DIN) with other test standard setting is different, not pure is the conversion problem between units, so can t conversion.
